Spoolable small-form-factor RFID-enabled wristband

1. A wristband comprising flexible material formed into: a flag portion that comprises a radio-frequency identification (RFID) inlay embedded within the material; and a strap portion extending from the flag portion, wherein the strap portion is perforated in a line along a longitudinal axis of the wristband from a distal end of the strap portion that is distal to the flag portion to a hole at a proximal end of the strap portion that is proximal to the flag portion, such that the strap portion may be torn, from the distal end to the hole at the proximal end, along the perforated line, into two sections of equal dimension, which each extend from the flag portion.

2. The wristband of claim 1 , wherein a lateral width of the strap portion is less than a lateral width of the flag portion.

3. The wristband of claim 1 , wherein a lateral width of the strap portion is the same as a lateral width of the flag portion, such that the wristband has substantially uniform width.

4. The wristband of claim 1 , wherein the two sections of the strap portion are configured to attach to each other after the strap portion has been torn along the perforated line.

5. The wristband of claim 4 , wherein the two sections of the strap portion form a loop when they are attached to each other.

6. The wristband of claim 5 , wherein the two sections of the strap portion are attachable at a plurality of positions, such that they may form a loop having any diameter within a range of diameters.

7. The wristband of claim 4 , wherein the two sections of the strap portion consist of a first section and a second section, and wherein the distal end of the first section comprises a fixation mechanism which is attachable to at least a portion of the second section.

8. The wristband of claim 7 , wherein the fixation mechanism comprises an adhesive patch which can be adhered to any portion of the second section, and wherein the distal end of the second section also comprises an adhesive patch which can be adhered to any portion of the first section.

9. The wristband of claim 7 , wherein the fixation mechanism comprises a buckle, and wherein the second section comprises at least one opening configured to receive the buckle.

10. The wristband of claim 1 , wherein the RFID inlay is embedded between two layers of the material.

11. The wristband of claim 1 , wherein the flag portion comprises at least one printable region on at least one external surface of the flag portion.

12. The wristband of claim 11 , wherein the flag portion comprises a fold line along the longitudinal axis from the hole to an end of the wristband that is opposite the strap portion, such that the flag portion may be folded in half along the fold line.

13. The wristband of claim 12 , wherein a single external surface of the flag portion comprises two printable regions, and wherein each of the two printable regions is positioned on an opposite side of the fold line than the other of the two printable regions.

14. The wristband of claim 12 , wherein a single external surface of the flag portion comprises a printable region on one side of the fold line and has a display on the opposite side of the fold line.

15. The wristband of claim 14 , wherein the single external surface also has a fingerprint sensor on the same side of the fold line as the display, and wherein the fingerprint sensor is configured to sense and authenticate a fingerprint.

16. The wristband of claim 15 , wherein the display is configured to indicate a result of an attempt to authenticate a fingerprint sensed by the fingerprint sensor.

17. The wristband of claim 11 , wherein the display is configured to display information related to a wearer of the wristband.

18. The wristband of claim 17 , wherein the information comprises medical information.

19. A spool of wristbands comprising: a plurality of wristbands wound around a cylindrical core, wherein each wristband comprises flexible material formed into a flag portion that comprises a radio-frequency identification (RFID) inlay embedded within the material, and a strap portion extending from the flag portion, wherein the strap portion is perforated in a line along a longitudinal axis of the wristband from a distal end of the strap portion that is distal to the flag portion to a hole at a proximal end of the strap portion that is proximal to the flag portion, such that the strap portion may be torn, from the distal end to the hole at the proximal end along the longitudinal perforated line, into two sections of equal dimension, which each extend from the flag portion, wherein each of the plurality of wristbands is joined to at least one adjacent wristband by the material, and wherein the material is perforated, in a line along a lateral axis that is perpendicular to the longitudinal axis, at a boundary between each adjacent wristband, such that each wristband may be torn from each adjacent wristband along the lateral perforated line at the boundary between each wristband and each adjacent wristband.

20. A method of manufacturing a spool of wristbands comprising: embedding an RFID inlay within a material at a plurality of fixed spatial intervals; perforating the material in a longitudinal line, along a longitudinal axis of the material, at a plurality of fixed spatial intervals, to define two separable sections of equal dimension; punching a hole in the material at one end of each longitudinal line; perforating the material in a lateral line, along a lateral axis of the material that is perpendicular to the longitudinal axis, at a plurality of fixed spatial intervals, to define separable boundaries between the wristbands; and spooling the material around a cylindrical core.
